except local file management it's good support – Canvas Student Review

It is really useful app. You can even upload the assignment like videos, audios, docs. However, it lacks the local file and data cache management. Can you imagine it takes up to 800MB of the storage. You have to delete and reinstall. Moreover it seems each time you click the file, it will download the file. It is duplicate process.
